Indenoisoquinoline topoisomerase I (Top1) inhibitors are a novel class of anticancer agents. Modifications of the indenoisoquinoline A, B, and D rings have been extensively studied in order to optimize Top1 inhibitory activity and cytotoxicity. To improve understanding of the forces that stabilize drug-Top1-DNA ternary complexes, the five-membered cyclopentadienone C-ring of the indenoisoquinoline
茚并异喹啉拓扑异构酶 I (Top1) 抑制剂是一类新型抗癌药物。茚并异喹啉 A、B 和 D 环的修饰已被广泛研究,以优化 Top1 抑制活性和细胞毒性。为了加深对稳定药物-Top1-DNA 三元复合物的作用力的理解,茚并异喹啉系统的五元环戊二烯酮 C 环被六元氮杂环取代,产生二苯并[ c,h ][1,6 ]naphthyridines 通过新途径合成并测试了 Top1 抑制。这导致了几种化合物在许多癌细胞系中具有独特的 DNA 切割位点选择性和有效的抗肿瘤活性。
